IMPROVEMENT IN ELASTIC LINK'. FOR CLIEW'IS.l

The Schedule referred to in fluege Letters Patent and making part of the same.

To (Illu-710m it may concern.-

Be it known that I, LoUis FLmDxnn, of Cleveland, in the county of Cuyahoga, and State of Ollio, have invented 4a certain new and improved Elastic Link for llow-Oleris; and l do hereby declare that the following is a full and complete description of the same, reference being had to the accompanying drawings, maki ing part of this speciiication, in which- Figure l is a top view of the link.

Figure 2, side view.

Like letters of reference refer to like parts in the different views.

This invention has for its object the relief from sudden jar or strain upon the team, in consequence ofthe plow becoming suddenly arrested, by stelles or roots, while being iu use, thereby preventing the team from being iujured,'the harness and plow from being torn and broken.

1n the drawing- A represents the front end of the plow-beam, and

l5, the clevis, both of which are or may be constructed in the ordinary way. l

Attached to said clevis isv a stay, or yoke, C, by means of the pin a.

D is a rubber spring, one end of which is secured to the adjustable cross-bar E, whereas the opposite one is attached to the end of the link.

Said cross-bar is'iitted loosely in the yoke, so that it is allowed to move longitudinally therein, as will hereinafter be shown.

1" isa hook, the stem of which penetratesaud passes through the'spriug andcross-bar, and secured to said bar by a unt, Ur. v

Having thus described the constructionalul arrangement of the link, or coupling, its practical operation and use will now be described.

1t is' well known to the practical farmer, that in plowing stony or rooty ground, the plow is often suddenly arrested iu its course. by contact witlrsome hidden stone or root, the consequence ot' which is, that the plow-point is sometimes broken ol'f, or other parts ofthe plow-gearing are i lore or less injured, and not un'ti'equently the harness is badly torn from the team,

involving much loss of time, and consequent expense in the work of plowing.

Also the team, in consequence of such sudden stopping in their progress, receive inj nry in their shoulders,

by the. violence of the jerk and strain exerted upon them, which is of freijluent occurrence in stony and rooty land. They become tender and sore, and therefore unable to work.

To avoid these accidents to the plow and harness, and injury to the team, is the `purpose of this link, and to which the doubletree is attached, by means ofthe hook F.

Now, it will be obvious that if the team is suddenly stopped,in consequence of the plow being caughtby a stone or root, the violence ot' the motion will be broken by the elastic and compressible nature of the spring D, upon which it will be received, as the draught of the team is exerted upon the hook, thereby compressing the spring more or less, as the strain thereon may be.

exerted.

It will be obvious that this yielding of the spring to the force ot' the arrested progress ofthe team and plow will prevent its expenditure upon the plow and shoulders of the horses, hence no breaking ot` the one, nor injury to the other will result. `All will work freely and easily to the plow, team, and driver.

This link is equally applicable to all connections, when heavy draughts are made, and subject to sudden and violent activities, and for ordinary purposes, when an equal and'steady motion is had, it is alike applicable and useful.

This link is neat in appearance, simple in its coustruction and arrangement, and, when properly made, is strong and dura-ble.

\Vhatl claim as my invention, and desire to secure by Letters Patent, is-

The spring D, as arranged in combination with the adjustable cross-bar E, yoke, or frame C, and hook F, in the manner substantially as and for the purpose set forth.
